By Ian Graham BELFAST - Northern Ireland's restrictive abortion laws are in breach of human rights by failing to provide exceptions in the case of fatal foetal abnormality and sexual crime, Belfast's High Court found in a landmark ruling on Monday. Unlike other parts of the United Kingdom, abortion is banned in Northern Ireland except only where the life or mental health of the mother is in danger. After four months of deliberation, Judge Mark Horner upheld a challenge by the Northern Ireland Human Rights Commission that the laws breached the European Convention on Human Rights.
